  • the invention provides a portable, foldable electric tricycle as specified in claim 1.
  • the present invention Compared with the existing technology offerings on the market, the present invention has the following advantages: As the present invention can be easily folded into a normal trolley suitcase shape and size, it is convenient for the users to take it onto buses and trains. Instead of driving cars into downtown, if takes the option of riding this electric tricycle, folding it to trolley suitcase when taking public transportations, then riding it again as tricycle to offices or destinations downtown, hence, traffic congestion and air pollution problems in urban areas will be reduced significantly. Furthermore, it will save huge amount of energy and money. In addition, when folded to trolley suitcase shape, its volume is largely reduced. This combined with the wheel-dragging function of the trolley suitcase enables it enters the offices, hotels and shopping malls with the users. Compared with driving own cars, this invention can be kept by the side of the users at all time, which reduces the chance of getting lost and saves parking spaces in urban areas. In addition, the invention can also be folded to a chair mode, which further increases its applications.

  • a handlebar torque transmission male component 12 is attached to the lower end of controlling handlebar 10, and a latch hook 11 is installed to the front of the foldable handlebar base 9.
  • the foldable frame 2 When folded into a tricycle state from trolley suitcase shape, the foldable frame 2 is folded to the front of the seat case 1, the controlling handlebar 10 is folded to an upright position, the front wheel fork 5 is folded to an upright position, the foldable handlebar base 9, the foldable front wheel base 3 are interlocked with each other, and are both interlocked with the foldable frame 2 by snapping the hook locking component 4 and the latch hook 11; the front wheel torque transmission female component 6 at the upper end of the front wheel fork 5 in interlocked with the handlebar torque transmission male component 12 at the lower end of the controlling handlebar 10.
  • controlling handlebar 10 When controlling handlebar 10 is turned an angle, the torque will be transmitted to electric front wheel 7 through handlebar torque transmission male component 12 and front wheel torque transmission female component 6, thus the trike will turn accordingly.
  • the structures of the backrest 14 frames and the rear wheel 17 are designed as a group forming a four bar linkage.
  • the above interlocking system between the backrest 14 and the rear wheel 17 as well as their folding towards seat case 1 are achieved by the following steps: Please refer to Figs. 1 , 3 and 6 .
  • the backrest 14 is hinged to the seat case 1 at both left and right sides of the frame. Both sides are completely symmetrical, and so as to the connected parts. Therefore only one side is described below:

  • a foldable rear wheel stand 16 is hinged to the lower end of the seating base 1 at a rear wheel stand hinge joint 161, and the rear wheels 17 are attached to the foldable rear wheel stand 16.
  • the lower end of the foldable rear wheel stand 16 is hinged to the connecting rod 15 at a rod lower end hinge joint 151.
  • the front end of an elastic pushing rod 18 is hinged to the lower part of the backrest 14 at the backrest edge joint 143, and the elastic pushing rod 18 is hinged to the back of seat case 1 at a pushing rod stopping joint 181.
  • the backrest folding joint 142 and the rear wheel stand hinge point 161 are the fixed link.
  • the foldable beam 13 is hinged to the front of the seat case 1.
  • the foldable beam 13 When the vehicle is folded into trolley suitcase shape, the foldable beam 13 is folded parallel to the front of the seat case 1, thus, the foldable beam 13 acts as the handlebar of the trolley suitcase; when folded into chair state, the foldable beam 13 is folded vertically to under the seat case 1, thus, the foldable beam 13 acts as the front legs of chair; when folded to transportation or storage state, the foldable beam 13 is further folded toward the seat case 1, thus the foldable beam 13 takes little space for easy transportation or storage (shown in Fig. 6 to 8 ).
  • the vehicle is powered by battery 21, which is placed inside the seat case 1; a seating cushion 20 is attached to the surface of the seat case 1, as shown in Fig. 1 .
